Actually that is not weird MOHO.

Your attention/focus should be on the target with both eyes open. The pin should be secondary which most of the time this tends to put the focus in the middle in a kinda floating mode...I guess I can't explain it. Your main and goal should be on the target, apply back tension....when the shot goes off as a suprise you'd be shocked to learn the pin could be off but the arrow will not be, if you focus strickly on the pin, I doubt that's the case.
